From Marion Lake, we traversed the south slope of Pt 6480+, staying in the relatively open areas, opposite the cliffs. (Staying directly under the cliffs should go fine too, though the trees are thicker.) This led us to a scramble over jumbled, half-snowed-over talus on the northeast slope of Mission Peak; we angled for the north end of the cliffs.
For the return trip, we descended FR330 to the last hairpin, then struck out northeasterly, along Redwic's route. We followed the tracks of a skier who knew how to chain together a number of clearings, saving us considerable time - though some of the open slopes we traversed could present an avvy risk in deeper snow.

Headed up from the ski resort parking lot. We succeeded in finding a bit of sun somewhere in Washington, but our luck ran out before the summit. We didn't need snowshoes until the ridge. Great glissading on the way down.
